1.2V TO 37V 1.5A DUAL ADJUSTABLE POWER SUPPLY USING LM317 & LM337

1.2V TO 37V ADJUSTABLE DUAL POWER SUPPLY USING LM317-LM337  (1)

This project is a solution to power up most of devices or projects requiring dual (+/-) adjustable power supply. The circuit is based on LM317 positive and LM337 negative voltage regulators. LM3X7 series of adjustable 3 terminal regulators is capable of supplying in excess of 1.5A over a 1.2V to 37V DC output range. On board TO220 Package with heat sink can handle maximum load current. Board provided with two on board preset to adjust the voltage.
